1 Claim. (Cl. 15157) This invention relates to an improved scraping andcalking tool for use when scraping and calking the decks of a boat, itbeing one object of the invention to provide a tool including a handleand 2 while the tool is in use. The forward end of the handle is formedwith a longitudinally extending socket 3 to receive the shank of thetool carried by the handle, this socket being rectangular in detachabletools which may be selectively apcross section so that when the shank orthe tool plied to the handle and firmly held so that they is fitted intothe socket it may not turn out of will not slip out of connection withthe handle proper relation to the handle.

or out of proper relation to the handle while in The scraper is shown inperspective in Fig. 4, use. and, referring to this figure, it will beseen that Another object of the invention is to provide a this scraperis formed from a bar of carbon steel tool of such construction that itmay be used while of appropriate width and thickness. The bar isstanding or leaning over instead of it being necbent intermediate itslength to form a blade 4 essary to kneel upon the deck. which isconnected with the rear portion 5 of the 7 Another object of theinvention is to provide a tool by a curved portion 6 projecting upwardlyscraping and calking tool of such construction from the front end of therear portion 5. This that a hose leading from a source of compressedcurved portion imparts added weight to the air may be mounted along thehandle and shank scraper so that the sharpened lower edge I of the ofthe tool in such position that an air blast blade 4 will readily cut thesurfaces of deck may be discharged forwardly to clear the deck or planksand also readily cut hardened tar protrudcalking slot of dirt during useof the tool. ing from a deck seam. The lower edge face 8 of Anotherobject of the invention is to provide the blade is ground diagonally toform the sharpa tool wherein the scraper is of such formation ened edgeI and, from an inspection of Fig. 1, it that it has added weight andalso sufiicient rewill be seen that when the scraper is in use, thesillency to prevent it from being bent or broken edge face 8 is parallelto and rests flat upon the when in use. deck planks. It should also benoted that the Another object of the invention is to so form angle atwhich the blade extends is such that the the calking tool that it mayclear the bottom of a sharpened edge has a planing action whenscrapcalking crack or groove between deck boards ing a deck or removingprotruding tar from a deck and also out side walls of the crack orgroove and seam.

This improved scraping and calking tool has a thDuring usle of thescrapel ll? is desirable to have handle I which is of such length andthickness e dec Geared of scripmgs and other dirt that it may beconveniently held in a persons Therefore havmg a nozzle may be hand anddeck boards scraped or Gaming grooves extended longitudinally of thehandle and mountcleared and undercut While standing and leaned under thehandle and the rear portion of the ing forwardly somewhat.

The nozzle willthus be supported under the rear portion 5 of the scraper in suchposition that air discharged from the nozzle will strike the blade 4 andso'spread that it will clear the deck of shavings and other dirt.

In Figs. 5, 6 and 7, a calking tool is applied to the handle. This toolI! is formed from a bar or strip of carbon steel of suitable width andthickness. The bar is bent in spaced relation to its front end to form ablade I8 which extends downwardly from the body IQ of the tool and iscurved longitudinally, as shown in Fig. 5. The lower end of the blade isground to form a beveled edge face 2| having a cutting edge 2| along itsfront, and side faces of the blade are sharpened along their front edges22. Since the blade is sharpened across its lower end and along its sideedges it may be disposed within a calking groove 23 of a deck 24. Sincethe blade I8 is sharpened along its lower edge, the bottom of a calkinggroove may be cleared and deepened if necessary, and since the blade issharpened along its side edges, the sides of the calking groove may besmoothed and under cut so that when tar is poured into a groove andhardens, it will be firmly held in the groove. After the tar hashardened the portion protruding from the calking groove is removed witha scraper of the construction shown in Figs. 1 through 4, the blade ofthe scraper being appreciably greater in width than the calking groove.

This improved calking tool is applied to the handle I in lieu of thescraper and has its rear end formed with a shank of less width than thebody of the calking tool and of such dimensions that it fits snugly intothe socket 3 of the handle. Openings 26 are formed through the shank toreceive securing bolts l2. Shavings and other dirt is removed from thecalking groove by an air blast delivered from the nozzle ll of the airhose extending along the handle and held in place by clamps carried bythe handle and the calking tool.

Having thus described the invention, what is claimed is:

An implement of the character described comprising a handle, a scraperformed from a metal bar of greater width than thickness and having itsrear portion constituting a shank connected with the front end of thehandle, said bar being bent intermediate its length to form a flat bodyand a blade extending downwardly at a rearward incline and formed with acutting edge across its lower end, clamps carried by said handle and thesaid shank and extending downwardly therefrom, and a hose extendinglongitudinally of the handle and having a nozzle at its front end, thesaid hose and its nozzle passing through and supported by said clampsunder the handle and the shank with the nozzle directed forwardly inposition for discharging air against the rear face of the blade.
